[Catalyst] Memory usage with FCGI? Server running out of RAM

[Denny]

I run a server with 18 separate installs of ShinyCMS running, with at least 3 and sometimes 20 processes per install.  122 perl-fcgi processes in total.  They look a bit bigger than most of your processes. I've got 8GB of RAM, and I'm pushing up against the edges of it a bit, but I don't usually have any problems.

Hope that's useful info!
